GRAIN-SHOOKER.

Specification of Letters Patent. Patented Sept. 10, 1912;

Application filed October 1, 1908, Serial No. 455,621. Renewed July 23, 1912. Serial No. 711,191.

To all whom it may concern:

l 3e it known that I, PEARL WILSON SHAR a citizen of the United States, and a resident of Bowbells, in the county of \Vard and State of" North Dakota, have invented a new and Improved Grain-Shocker, of which the following is a full, clear, and exact description.

The purpose of theinvention is to provide a grain shocker adapted for attachment to any grain binder and soc'onstructed that the bundled grain is delivered from the binder platform to a receiving disk wherein the bundles are grouped and held in predetermined arrangement around a conical support, until a suitable quantity of bundles have been thus assembled, after which the operative mechanism'of the shocker is automatically set in motion and a shock con veyer automatically grasps the assembled bundles and sets them on the ground in the form of a shock. A

It is a further purpose of the invention to provide simple and reliable means for automatically controlling and timing the shock conveyer in such manner as to first bring the conveyor, while in its open position, down over the assembled bundles,-nexttoclose upon the bundles and lift them as a unitary mass from their supports, and then to carry the shock thus formed to one side of the attachment, deliver the shock in standing position upon the ground, and release the shock; the conveyer being finally restored to its first position ready for another opcration.

It is. also a purpose of the invention to accomplish the above-mentioned results while the machine is being moved bodily along through a field.

The invention consists in the novel con struction and combination of the several parts as will be hereinafter particularly described in the drawings, in which similar characters of reference designate corre sponding parts in all the views.

Figure 1 is a side elevation of the machine complete; Fig. 2 is a rear elevation of the same; Fig. 3 is aplan view of the rear portion of the shocker; Fig. 3 is a frag-- mentary plan view of the revoluble bundle receiver and parts immediately associated with it. Fig. 4 is a sectional view of that portion of the shocker which directly operates the conveyer and locking arms for the shock conveyer; Fig. 5 is an enlarged ver tical section through the platform upon which the bundles are placed, and the conical support for the bundles carried thereby; Fig. 6 is a rear elevation of the base of the shocker and a side elevation of the shock carriage, shock conveyer and connecting parts carried to one side, the shookconvever being closed, but otherwise occupyingthe position it assumes in order to deliver the shock; Fig. 7 is a detail view of one of the cam gears that operate the shaft used for operating the conveyor and lock ng arms; Figs. 8 and 9 are sectlonal detail vice-s of the trip device for the owcr shifting mechanism and show a portion of said mechanism; and Fig. 10 is a section on the line 10-1O of Fig. 3, looking in the direction of the arrow.

A represents the bed of the attachment upon which a rest 9 is erected at or near the center, and this bed is supported between its ends by aid of a driving wheel B, located about centrally between its sides and rolling upon the ground. The bed is further supported by caster Wheels 12, journaled in suitable bearings 11. At the rear of the bed A (see Fig. 3) a floor a is con structed so as to serve as a platform, and mounted upon this platform adjacent to its left-hand side is a segmental rack 13. A revoluble shaft 14: is iournaled in suitable bearings 14, carried by the bed A, these bearings being located beneath the platform (1. Upon said shaft two bevel gears 1'5 and 16 are secured. The. driving wheel B is secured upon an axle B mounted in suitable bearings 18, and disposed slightly inside of the rim of the said wheel B a bevel gear 17 is securedto the axle, as shown in Fig. 3. A.

shifting lever 19 is pivoted upon the right I hand bearing 18 and movable horizontally.

This lever is adapted atcertain times to control a transmission of power from the axle B to the drive shaft 14. This shifting lever, adjacent to its rear end is connected I by a. pin 21 with a box 20, the latter being mounted to slide in bearings 22, as is hown 1 are 1n l i s. 1, 3 and 10. The bearings I secured upon the under side of a bracket 10, the latter being mounted rigidly upon the bed A. The bracket 10.is provided with a slot l0" through which the pin :21 extends. The rear end of the said shifting lever 19 is flattened and is slidably supported upon a bracket Ql and arranged to enter a slot or recess therein, as is shown in Figs. 3, 8 and 9.

A pin 25 is attached to the rear end of the lever 19 and is encircled by aspring 25 which presses against the bracket The in 25 extends through the bracket 24, and is slidable relatively to the same. The shif ing lever .19 is made of spring steel and is pivoted on the right hand bearing 18. The spring 25 acts to restore the lever 19 to its normal position as soon as the rear end of this lever is raised out of the recess 2-3 in the bracket 24, by the action of a hinged trip arm 87 hereinafter more fully described. A revoluble shaft :26 extending in the general direction of the length of the bed, is adapted to communicate motion from the revolublc axle B to the shaft 14. The shaft 26 is journaled in the sliding box 20, and in arear fixed box 27, having slight lateral movement therein, as is indicated in ig. 3. A bevel pinion 28 is secured upon the'forward end of the shaft 26 and is adapted to mesh with the gear 17 on the axle B. but is normally held out of mesh by the aforesaid shifting lever 19.

At the rear end of the said driven shaft 26 a second bevel pinion 29 is secured, and the latter is at all times in. mesh with the bevel gear 16 on the drive shaft 14, as is shown in Fi 3. The shifting lever 19 is actuated by the revolution of a combined shock receiver and stacker, comprising a tray 0 and a cone C. This combined shock receiver and stacker is so constructed and arranged that after it has received a suitable number of bundles it will, in a manner to be hereinafter describethcause the axle I3 and the drive shaft 14 to be coupled together for such a length of time as will permit the shocker to remove and deposit the collected bundles and return to its normal position.

A tubular post 30 (see Fig. 1, left-hand portion) is erected upon the table at a point from which the radius of the segment rack 13 is struck, and is provided at its upper end with a ball bearing table 31. Upon. this table a carriage D is mounted to revolve, its bottom portion 32resting upon said balls or rollers. T he travel of the carriage D is limited a foot 39) at its lower rear portion, this foot 32- extending underneath the rack 13, as indicated in Fig. 6, and serving to brace the revolving carriage as well as to serve as a limiting stop for preventing 8X- cessive turning movemen of said carriage.

The carria e D may be of any suitable construction, but is usually rectangular and of skeleton formation, as illustrated. shaft 325 is journaled in suitable bearings upon the upper rear portion of the carriage D, as is shown in Figs. 1, 2 and (3. This shaft 1 term a cam shaft. It carries a large cain E for raising and lowering the conveyer of the shocker, and a gear 15 adapted to bring about the rotary movement of the carriage D. The large cam E is secured rigidly to the shaft 33 and is practically segmental in general contour, its curved pcriphery being concentric with its center, but in one edge, normally the forward edge, which would be otherwise a straight edge, a recess 3-1 is produced, the wall of this reoess coming generally to a point at one side of the center of the cam, as is shown in Fig. 1. A gear wheel 35 is secured upon the cam shaft 33, forming one of a chain of gears including the gears 35 36 and 38, shown in Figs. 1 and 6. The gear 36 is mounted upon a shaft 37, the latter being supported by hangers 37 which extend forwardly from the rear portion of the revolving carriage. The gear 38 is carried by a shaft 39 which is mounted upon the lower portion of stepped bearings 39, shown in Figs. 1 and 6, and is located at or near the central portion of the said carriage. The shaft 39 carries a bevel. gear 4.0 secured to it, this gear meshing with a bevel gear 41, carried by a short vertical shaft 12. This shaft 12 extends loosely down through the tubular post 30, and is provided at its lower end with a bevel gear 13, that meshes with the bevel gear 15 on the drive shaft, so as to impart a rotary movement to the camshaft 33. A shaft 1-1- is j ournaled in suitable bearings at the forward portion of the carriage I), about midway between its top and bottom, as is shown in Figs. 1 and 6, and on this shaft a sprocket wheel 15 is secured. The sprocket wheel 45 is connected by a chain belt 16 with a sprocket wheel 47, this sprocket wheel. forming a portion. of the hub of the gear E, as is shown in Figs. 1 and 2. The shaft 4.4 carries at each end hereinafter described. These gears have direct operative connection with the shock conveyer, also hereinafter described. The shaft 4. 1 is driven from the shaft 39 by a train of gearing shown in Figs. 1, 2 and 6. This train of gearing consists of a gear 38 upon the shaft 39 (see Fig. 2) a meshing gear 36 upon a shaft 36 a gear upon a shaft 35, and a gear 3 1 upon the shaft all of the auxiliary shafts being mounted upon the stepped bearings 39 The gear E is loosely mounted upon the shaft and is provided with toothed seg ments 6 and e, diametrically opposite each sides of the gear E, as shown in Fig. 1..

This gear E is adapted for turning the car'- riage D so as to alternately bring the. shock en iveyer from a position to receive a shock to a position to deliver the same and return it to normal position. This is accomplished as follows: A shaft 49 is vertically journaled at the rear of the carriage D, as shown in 1, 3 and (3. This shaft carries a bevel pinion 48 at its upper end, to be engaged by the segments 6 and e, and a second bevel pinion 50 at its lower end. The lower pinion 50 engageswith a corresponding beveled pinion 51 at the rear end of a short horizontal shaft 52, mounted in suitable bearin upon the carriage D, and this shaft provided with a plain pinion 53, that engages the teeth of the rack 13. In the operation of this portion of the device, the toothed segment 6' acting on the shaft 49, swings the support for the bundle carrier (to be hereinafter described) by the movement of the carriage D, at rightv angles to the body of the device to deposit a shock on the ground, as is shown in Fig. 6. The segment a now reverses the movement of the carriage D, returning the support for the shock conveyor to its normal position shown in Fig. l.

The bundle receiver C, shown in Fig. 5, and located at the forward portion of the device, as shown in Fig. 1, is in the form of a dished disk and turns upon a cross bar 5 L.

This cross bar is secured to the frame A,

and is attached to a pivot pin 55, that turns in said cross bar and is provided with a bevel gear 56 at its lower end. The bundles when placed upon the tray C rest against the cone C and are held in position by pivoted, weighted prongs 57 having their pivots within the cone and their points extending out through openings 58.

The stacker and bundle receivers are usually driven in the following manner: A gear 59 is made to mesh with the gear 56, the gear 59 located upon the inner end of a shaft 60 mounted in bearings beneath the frame A, being provided at its outer end with a sprocket wheel 61 connected by a belt (32 with a pulley 3 on a shaft- 64 mounted on the platform 65 of the binder, and driven therefrom in any suitable manner.

Beams 66, of any desired material and suitably spaced, are carried from the main frame A, in the direction of the binder platform '15, as is shown in Fig. 3 and upon said beams adjacent to the bundle receiving disk C, opposing vertical shafts 67 and (38 are mounted to revolve. These vertical shafts are in two sets, and a platform 69 is laid between them on the beams 66. The shafts U7 and 68 are braced from their'upper ends by rods 70 that are secured to the main frame A, as is shown in Fig. 3. The shafts 67 and 68 at each side of the platform 69, carry endless conveyer aprons 71, that convey the bundles delivered to the platform 69 to the tray C, where they are supported and lean against the cone C, being held in position by the spurs 57. The bundles from the binder platform fall into an upright chute 7 2, that inclines'in the direction of the platform 69, to which the bundles are directed, and a spring arm 73 at the top of the chute 7 2 extending some distance over the binder platform, serves to direct the butts of the bundles downward and hold them in upright position in their passage to the said platform 69.

At 73 is a bundle which is thus being guided by the spring arm 7 3. This spring arm is curved and strikes the butt of the sheaf a little below the band and holding the butt untilthe same drops downward, thereby tending to set the sheaf in a perpendicular position, the momentum of the sheaf forcing it forward.

A longitudinal shaft 7% is mounted in suitable bearings 75 upon the beams 66 and, as is shown in Fig. 2, the shaft 74 carries bevel gears 76, that mesh with corresponding gears 77 on the eonveyer shafts (37. The rearmostgear 77 meshes with a gear 79 upon a transverse shaft 78, as is shown in Figs. 2 and 3, the said shaft 78 having a second gear 79 at its inner end. Motion is communicated to the shafts 67 and 78 by meshing a gear 80 with the said gear 79. The gear 80 is upon the forward end of a line shaft 81, journaled in suitable bearings 82 and 83 in the main frame A. At the inner end of the line shaft 81, a bevel gear 84 is secured, and meshes with a like gear 85 upon the axle B, as is shown in Fig. 3.

As has been stated, the connecting shaft 26 is normally out of operative engagement with the axle B, but when the tray C has been properly loaded, the said axle and the said shaft are automatically coupled together by means of apin in the bottom of the tray, which engages the forward free end of the shifting lever 19, causing it to slidethe box 20 inward and thus bring the gears 17 and 28 into engagement, thus setting the carriage D and parts carried thereby in motion. As the carriage D is nearing its normal position on its return trip after setting the shock on the ground, a hinged trip-arm 87, connected with the carriage D and provided with a foot 88, engages the inner end of the shifting lever 19 and lifts it from the notch or recess 23 in the bracket 24:. By this operation, the spring 25 which, up to this time is held undertension, is released and said springrestores the lever to its normal position and the aXle'B and shaft 14- are thus disconnected. According to Fig. 8, the carriage D is traveling toward the left, and the trip arm. is about to drag over the top of the lever 19. When, however, the

vi L. is

carriage afterward moves to the right, the

foot 88 will raise the lever 19.

in connection with the carriage D, 1 cmploy a conveyei' guide arm 1*, having a channel or groove in its upper face, which arm, at its rear end, is pivoted by means of a pin. 90 in bearings 89 secured to the front upper bar 0? of the carriage D, as is shown in Fig. 4. A conveyor shifting arm F is mounted to slide in the conveyor guide arm F and the arm 1" is provided with a rack 91, in the upper face of its inner end and preferably at the left of the conveyor shifting arm F, a conveyor trip 211111 E is located, as is best shown in Figs. 1 and The rear end of this arm l5 slides upon the pivot 90, and in the upper face of its inner or rear end, is provided with a rack surface 92 corresponding to that of the guide arm 1?.

Pinions 93, 91 respectively, engage the racks 91, 92, as will be understood from 71g.

1. The pinion as is mounted upon a shaft 95, the latter carrying a bevel pinion 9%. The pinion is mounted. upon one end of a shaft 95 the opposite end of this shaft carrying a bevel pinion The siafts 95, 95 are supported in bearings, the latter being carried by the upper front portion d of the carriage D.

The shitting arm 1*" extends forwardly beyond the guide arm F, and at its outer end is provided with a lug 98 upon which an elbow lever 99 is fulcrumed, and the outer end or the trip arm or rod F is pivoted to the upwardly-extending member of said lever. Triangularly-arranged braces 100 and 101 are secured to and extend down from the shifting arm F at its Outer end and said shifting arm F, at its outer end, carries a shock conveyor G, or device for lifting and transporting the shock; The lower portion of this device consists of op posing jaws 5 and g pivoted to an upper structure consisting of opposing angular members 102 having lugs 103' adjacent to their lower ends, and the two said members 102 are jointly pivoted to the braces 100 and 101, as is shown at 104 in Figs. 1 and (3. The upper ends of the members 102 of the conveyor G, have a toggle connection with the elbow lever 99, brought about by links 105 pivoted to said members, and a single link 106 that pivotally conne ts the links 105 with the horizontal member 01 the lever 99, as is shown at 106 and 106 The jaws g and g are provided at their free ends with segmental. gripping members 10?, adapted to receive between them a shock. The pivoted connection between the jaws g and g, and the upper section 102 of the conveyor G is designated as 108.

Each jaw g and g is provided with a lug 109 adjacent to its pivot, and springs 110 engage the gaws, normally maintaining shock,

them in open position, as is shown in Fig. 1. l i hen the shock conveyor G is in position to grasp a shock, its downward movement is limited by the guide arm F engaging the rest 9, a recess 111 being provided in said arm to steady it when thus resting.

lit the inner end. of the guide arm ll, a. roller 112 is mounted. This roller is adapted for engagement with the periphery of the main cam 11, as is shown in Fig. l. l-Vhen this roller is engaged by the plain peripheral surface of the cam E, the guide arm F and connected parts will be elevated, but when the roller engages the recessed portion 3d of the cam, the said arm will drop, so as to bring the conveyor G over the shock upon the revolving platform or disk G, or to convey the shock to the ground, the arm F acting first as a clamping medium and then a discharging mediuin.

The gripping and releasing action of the shock conveyor is brought about as follows: Shafts 113 are journaled in any approved manner at each side 01" the upper forward portions of the carriage D, having beveled pinions 11 1 at their upper ends and corresponding pinions 115 at their lower ends. The shafts 95, 95 are intermittently -riven through the medium of the shafts 113 by the shaft 1 1 heretofore mentioned. To this end, a wheel H is secured at each end of the shaft 14. is shown in detail in Fig. 7. Each of said wheels is provided with toothed segments facing in opposite directions and designated at the left hand side of the device, or that side at which the trip arm F is located, as 116 and 117, while corresponding toothed segments at the opposite side of the machine are designated as 116 and 117 The left hand gear wheel, however, is provided with an intermediate toothed segment 118, facing in the same direction as the segment 116. The segments 116, 116, 117, 117 are for the purpose of giving a sliding movement to the arms F and F while the seg ment 118 serves to give additional movement to the arm F That is to say, the vertical shaft 113 (Figs. 1 and 6) is first given a rotary movement in one direction, in order to cause the grippersto seize the and is a moment afterward given a rotary movement in the opposite direction, to release the shock, the time elapsing between these two rotary movements being the period consumed by the machine in shifting the shock to the ground. The toggle action of the links 105 causes the grippers, when once closed upon the shock to hold tightly upon the same, pers are momentarily released from control of the shaft 113.

It will be observed from. Fig. 4: that the pinion 93 is on thesection a: of the shaft 95 One of these wheels even when the gripand the pinion 94 is upon the section it, thus permitting one pinion to act independentlyof the other, although at times both act in concert. A suitable pole 119 is employed to connect the shocker with the binding platform of a reaper and mower.

When the formation of the shock is complete and the arms F- and F are lowered to receive the same, the short segment 118 at the left hand side of the machine ongages the pinion 115'at the same side, which action retracts the arm F and locks the jaws g and 7' around the shock. The guide arm F is then raised by the cam E, and

the carriage D is swung around from the distance between the machine-and the. shock,

due to the forward travel of the machine upon the ground while the conveyor fingers are rising fromthe shock. As the car-- riage D is returned to its normal position, the segments 116 and 117 draw the arms back to their normal positions ready for the next shock. It will be understood that the jaws g and g are released from the shock by the same factors that caused them to grip.

The general operation may be summarized as follows :Starting from the position indicated in Fig. 1, the arm F'is lowered,

the arm F is then moved inwardly to grip the shock, the arm F is next raised, the carriage is rotated, the arm F is again lowered, both the arms F and F are moved outwardly at the same time, the arm F is moved still farther outward to release the shock, the arm F is again raised, the carriagc is rotated in the reverse direction, and the arms F and F are moved inwardly together. This cycle of steps is repeated our and over as the machine is drawn forward upon the ground. The manner in which this is accomplished will now be stated. As the machine travels forward, the rotation of the ground wheel B causes the shaft B to turn in a clockwise direction according to Fig. 1. This causes rotation of the pinions 17, 28 and the shaft 26. The

shifting lever 19 is used to throw the gearing into and out of action, which it does by moving the shaft 26 in a lateral direction, crossing the general path of travel of the machine (see Figs. 3 and 10). The pinion 16 while in. action, turns in aclocltwise direction, according to Fig-1. Motion is communicated through the pinion 15 and shaft 42 and thence through the various gears shown in the lower left hand portion of Fig. 1, ultimately causing the shaft 1 1 to turn in a clockwise direction according to this figure. The sectors carried by the .shaft'fl (see Fig. 7) by acting upon .the

pinlon 115, cause the shaft 113 to rock first in onedirection and then in the opposite direction. Motion being communicated through the pinions 114, 96 to the horizontal shaft 95,'movements of this shaft cause the arm F to be thrust forward and afterward drawn backward. Motion being transmitted through the sprocket chain 46 to the sprocket wheel 47, the cam E is turned in a clockwise direction according to Fig. 1. The rotation of the cam E causes the tripping of the arm F. In the positions indicated in Fig. 1, the arm F is just ready to drop in order to grasp a bundle of sheaves carried by the machine. A further rotation of the 'cam- E willraise the arm F and the bundle with it. The rotary carriage is next turned a quarter of a revolution, so that the arm F, having raised the bundle, transfers the lat- -ter around to a right angle. The outer or free end of the arm being again raised' (due toaction of the cam E) the bundle is released and the arm is ready to be turned back into its original position, as indicated in Fig. 1. Thcrotation of the carriage is caused by the sectors ,6 acting alternately upon the. pinion 48 (lowerv left-hand corner of Fig. 1) which transmits power through the shaft 49, pinions 50, 51 and 53, to the rack 13. This movement of the carriage takes place in proper sequence relatively to the lifting and lowerin of the bundle. After the bundle is deposited upon the ground and before the gripping fingers are completely released from it, the machine-being inmo-tion, of course, travels forward a little distance before the bundle is completely released. The segmental rackse and e and the gear pinions 48, 50, 51, and 53 are so proportioned that the engagement of either segmental rack with the inion 4S corresponds to a degree of rotation of the frame D of a little more than degrees, this be ing the relative movement of the frame D and of the segmental racks, being simply a matter of gearing. It is desirable that the frame D shall be free to turn a little more than 90 degrees, although in practice this angular distance is sufliclent. The carriage D is rotated by the rack 6' while the arms F and F are being extended. The length of the rack 117 is equal to that of the sum of the racksllT and 118. Similarly the rack 11'? is equal in length to the Ind: 116. This arrangement is desirable in order that the racks 117 117. may be able to restore the arms F and F to the respective positions they occupied before they were extended.

The springs employed in connection with the conveyer fingers serve to make the tension on said fingers about equal for both large and small shocks.

The gears 113, 116, 117'are merely for F and F are controllable by the cam E qualified by-the motion of the carriage D.
